Visual representations are the first thing a consumer sees, and is why great games have great visuals. Simply aiming to achieve a modest proportion of time consumed into graphics is not a bad thing, I for one would rather have nice visual representations to guide my eyes and allow me to understand the game and mechanics faster (I am a visual person). When the creators seek to make graphics the selling point rather then the eye-catcher, we start to see problems.
however games 'dumbing down' are an entirely different topic that is, in reality, quite an extensive one. This sense of 'dumbing down' has started to become a common form of attack at games that gamers from older generations see as too easy. In reality, a lot of it is simply different. I find that the perfect new formula for a gaming system is to make it simple but versatile. For example, gw2.
We all know gw2, it had a controversial time when it was launched and kept to quite a lot of its hype. I've never gotten into mmo's before, but gw2 I just attached to. There were various reasons for this, but a main one was the fighting system.
Simple, yet versatile.
I had 5 main abilities, with an extra 5 special abilities. That's 10 abilities I have to focus on, instead of 40 different unnecessary additions that mmo's define themselves on. Yet their were still as many choices as any other mmo, it maintained its versatility.
Additionally, many things that are considered 'dumbing down' is actually more for convenience. For example, Skyrim changed from earlier elder scrolls in its quest system by having a tracker for the destinations within that quest. This isn't 'dumbing' the game down, but rather providing convenience for the player. I'm sure older elder scrolls players will remember quests that had terrible directions, causing painful searching for hours that really was not pleasant in any way.
However, it is true that many games are dumbing down in addition to making a simpler system. This is because the gaming community has started to blow out of proportion, where gaming itself has become an excepted norm in most country's, and E-sports has become a competitive sport for many people. A lot of games are now focusing on this market, realising that a lot of this new intake is related to casual gaming. That's right, they want money and the money is in casual gaming.
This does not mean games are going to eventually reduce until we can't recognise an easy game from a hard one, it simply means that a majority of games will be focusing on a more casual market, leaving the hardcore market to thrive in its own space. I, for one, am looking forward to many games that I don't consider 'dumbed down'. Dark souls 2, here I come.
